The Rarity of the 1942 (12.5g) Caravela The reason this coin is so rare—even in the standard 12.5g weight—comes down to the chaos of World War II. The Mass Melt: Most of the 1942 mintage was never released or was recalled and melted down shortly after production. Because silver prices fluctuated wildly during the war, the Portuguese government pulled these coins back. Survival Rate: Only a tiny fraction of the original mintage survived in the hands of the public. It is widely considered the most difficult date to find for anyone trying to complete a 10 Escudos collection. Market Value: Because this is a "Key Date" that every Portuguese collector needs, the price is high regardless of the metal value. In VG (BC) condition, this coin alone can easily command $150 to $250. If it is in better condition (MBC or higher), it can reach $500 to $800+.
